Multifactor Graphical Password Authentication System using Sound Signature and Handheld Device
Every system uses text password but provides poor security. Graphical passwords on the other hand provide greater security and are easy to remember. In this paper, the authors present various authentication schemes using graphical passwords. These provide potential solution to the flaws of text as well as graphical passwords. In this system, they present two modes of graphical password authentication system i.e. offline and online. The offline mode consists of a graphical password integrated with sound signature, whereas the online mode focuses on Cued Click Point (CCP) based pattern using encryption and decryption.
